We just returned from Paris and while there we were in the need of more adapters. The BHV store on rue de Rivoli has all the adapters and converters you will need. I also bought a hair dryer while there. It makes it so much easier not needing an adapter. We stayed a few blocks from the Champs on the Arc de Triomphe end and found it not to touristy and great for walking, and great shopping.

We did a wonderful walking tour of the Marias with Eye Prefer Paris Tours. If anyone is interested I'll post their link.
